Windows & Doors in Southlake, TX
Window installation in Southlake rarely means pulling a stock unit off a shelf. The executive homes built across Southlake between roughly 1992 and 2015 feature arched transom assemblies, two-story fixed panels, and 8-to-10-foot entry door systems that were custom-ordered the day the house went up, and they’re custom-ordered again when they fail. What makes these jobs different is the soil: North Texas clay moves, frames rack, and seals break on glass that should have lasted another decade. Call (509) 265-6387 for a written price before any work starts.
Why Southlake Homes Are Different
Southlake’s housing stock skews heavily toward large semi-custom and fully custom homes built during the city’s rapid growth era between the early 1990s and mid-2010s. Those houses were designed with high ceilings and oversized openings, which means trapezoids, arched tops, and floor-to-ceiling glass assemblies that no distributor keeps in inventory. Every replacement job here starts with a measured survey, not a catalog lookup.
The clay subsoil is the silent variable on nearly every door job in Southlake. As slabs heave seasonally, heavy 8-foot entry doors bind at the header and thresholds gap at the sill. A homeowner who thinks they bought a defective door is usually looking at foundation movement, and the right fix is a re-hang or threshold adjustment quoted alongside the new unit, not after it’s installed. Spring hail events add another layer: Southlake sits directly in DFW’s hail corridor, and big glass assemblies take disproportionate damage during storm season. West-facing afternoon sun and 100°F summer heat also accelerate seal failure on the oversized double- and triple-pane units common across town.
Our Main Southlake Services
Two services account for most of the calls we take from Southlake homeowners: full door system replacements and whole-home window replacements. Both usually involve custom fabrication lead times and existing frame conditions that standard installs never see.
Door Installation in Southlake
Entry door systems in Southlake are heavier, taller, and more decorative than what you’ll find in average DFW production homes. A replacement often means rebuilding the rough opening, addressing a racked frame from clay soil movement, and setting a door that weighs several hundred pounds. We measure the existing structure, document every sightline reading, and specify the door by performance tier and opening size. The written survey and the final quote are the same document. See Door Installation in Southlake for full detail.

Window Replacement in Southlake
Window replacement jobs in Southlake often involve matching existing architectural shapes: arched tops, trapezoids, and two-story fixed panels that must be recreated to the original sightline. The homes in this market deserve exacting work, and the climate demands it: seal failure from temperature swings and hail damage to west-facing glass are the two most common reasons Southlake homeowners call us. See Window Replacement in Southlake for the full scope.

Before
AfterWindow Installation in Southlake

Window installation in Southlake means working with custom openings on homes built between 1992 and 2015, where arched tops, two-story fixed panels, and oversized trapezoids make off-the-shelf replacements impossible. The local climate accelerates failures too: intense west-facing sun and triple-digit summer heat bake seals, while spring hail storms crack insulated glass on the largest elevations. Our Window Installation process starts with a measured survey you keep, and the written price comes from that document, not from a catalog guess.
Single & Double Hung Windows
Signs you need it
Sashes that won’t stay up, fogged glass between panes, or visible rot at the sill joints are the usual signals on Southlake’s 1990s-era builds.
What it costs in Southlake
Single hung replacement windows in Southlake typically run $450 to $900 per unit; double hung units run $800 to $1,400 per unit installed.
How we do it
We pull the interior stops, remove the old sash and balance system, inspect the rough opening for plumb and level, then set the new unit with a sloped sill pan and insulating foam before trimming out and sealing the exterior.
3-Panel Sliding (3-Lite Roller) Windows
Signs you need it
Rollers that grind or catch, tracks that have worn through, or panels that no longer seal against the frame are common on Southlake’s wide openings.
What it costs in Southlake
Three-panel sliding window replacements in Southlake run $1,800 to $3,500 per opening, depending on overall span and glass package.
How we do it
We measure the span, panel count, and stack direction on site, remove the existing assembly, check the rough opening for racking, then install the new three-lite unit with new rollers, interlocking stiles, and a sealed frame.
What Window Installation Costs in Southlake
| Item | Typical range in Southlake |
|---|---|
| Single hung window (per unit) | $450 - $900 |
| Double hung window (per unit) | $800 - $1,400 |
| 3-panel sliding window (per opening) | $1,800 - $3,500 |
How long does window installation take in Southlake?
Most full-home window replacements in Southlake take two to four working days from tear-out to final trim, depending on opening count and whether custom units have already arrived. You’ll get a written schedule as part of the quote.
Will custom window sizes delay my Southlake job?
Yes, and that’s normal here. Southlake’s arched and trapezoid openings are made to order, with lead times running three to six weeks depending on the manufacturer line. We order the day the survey is signed and keep you posted on arrival.
Impact Windows & Doors in Southlake

Impact windows and doors in Southlake are a practical response to DFW hail season, not just a coastal-code carryover. Large glass assemblies on executive homes take the worst of spring storms, and impact-rated glazing holds the opening sealed when debris hits. Our Impact Windows & Doors work specifies products from CGI and CWS by performance tier, and every job includes a documented photo record at completion.
Impact-Resistant Windows
Signs you need it
Cracked panes from the last hail event, or west-facing glass that has already been replaced twice in five years, is the signal to upgrade to impact-rated glazing.
What it costs in Southlake
Impact-resistant windows in Southlake run $900 to $1,800 per unit installed, depending on size, frame material, and design pressure rating.
How we do it
We confirm the opening dimensions and exposure, specify the right design pressure rating for the elevation, order the laminated units, and install with the heavier frame anchoring that impact glazing requires.
Double Hung Impact Windows
Signs you need it
If you’re replacing double hung units and want the same look with rated glass, this is the product that keeps the architectural character while adding hail protection.
What it costs in Southlake
Double hung impact windows in Southlake run $1,200 to $2,200 per unit installed, with laminated glass and reinforced frames.
How we do it
We verify balance weights for the heavier laminated sashes, remove existing units, check square on the rough opening, then set the new windows with heavy-duty balances and a full perimeter seal.
What Impact Windows & Doors Costs in Southlake
| Item | Typical range in Southlake |
|---|---|
| Impact-resistant window (per unit) | $900 - $1,800 |
| Double hung impact window (per unit) | $1,200 - $2,200 |
| Impact entry door (per opening) | $2,500 - $5,000 |
Do impact windows really matter in Southlake’s climate?
Southlake sees damaging hail regularly enough that yes, impact-rated glass pays for itself by surviving storms that shatter standard units. Laminated glass also reduces noise and blocks more UV than conventional glazing.
What’s the difference between impact-rated and just tempered glass?
Tempered glass breaks into small pieces on impact; impact-rated glass is laminated, so the inner layer holds the pane together even when struck. For Southlake hail and storm debris, impact-rated is the better match. Call (509) 265-6387 for a written quote.
Energy-Efficient Windows in Southlake

Energy-efficient windows in Southlake are where most of our conversations start, because west-facing glass on these big custom homes bakes all afternoon in the Texas sun. The concrete benefit is lower cooling load through July and August, plus sealed units that don’t fog from the temperature swings between 100°F summers and ice-storm winters. Our Energy-Efficient Windows work specifies low-E coatings and gas fills to the exposure, not by default.
Low-E & Argon Gas Glass
Signs you need it
Rooms on the west side that run ten degrees warmer than the rest of the house, or fading on furniture near tall fixed panels, point to failed or absent low-E coatings.
What it costs in Southlake
Low-E with argon gas glass packages in Southlake run $480 to $1,100 per unit installed, depending on window size and frame material.
How we do it
We check the existing U-factor and SHGC on the units being replaced, match the new glass package to the exposure, and install with a full thermal break and perimeter seal.
ENERGY STAR Replacement Windows
Signs you need it
Condensation between panes, drafty frames on windy days, or an AC system that runs constantly from May through September are the usual signals.
What it costs in Southlake
ENERGY STAR replacement windows in Southlake run $600 to $1,400 per unit installed, with the exact figure set by size, style, and glass package.
How we do it
We measure each opening, confirm the orientation and shading, specify a window that meets ENERGY STAR criteria for the South-Central zone, and install with full frame insulation and exterior sealing.
What Energy-Efficient Windows Costs in Southlake
| Item | Typical range in Southlake |
|---|---|
| Low-E / argon gas window (per unit) | $480 - $1,100 |
| ENERGY STAR replacement window (per unit) | $600 - $1,400 |
| Insulated laminated glass (per unit) | $700 - $1,500 |
What U-factor should I look for in Southlake?
For Southlake’s heat-dominant climate, a U-factor of 0.30 or lower and an SHGC around 0.25 or lower makes sense on west and south elevations. We’ll write the exact spec for each opening into your quote.
Will low-E windows make my house noticeably cooler?
On a Southlake home with large west-facing glass, the difference is measurable. Low-E coatings reflect solar heat before it enters the frame, and sealed argon fills slow the heat transfer across the pane. Call (509) 265-6387 for exact pricing.
Sliding & Patio Doors in Southlake

Sliding and patio doors in Southlake live on the back or side elevations of large custom homes, and they take a beating from clay-soil movement. When the slab shifts, the track binds and the rollers wear. Our Sliding & Patio Doors work starts with a sightline measurement and frame check so the new door glides on day one and keeps gliding as the ground moves underneath it.
Patio Doors
Signs you need it
A door that needs a shoulder to open, visible gaps at the meeting stile, or water staining under the track after rain are all signals the frame has moved.
What it costs in Southlake
Standard patio door replacement in Southlake runs $1,800 to $3,500 per opening, depending on width, glass package, and frame material.
How we do it
We level the existing track plane, measure the clearance at both jambs, check for slab heave at the threshold, then pull the old unit and set the new door with shimmed jambs and a sealed pan.
Impact Sliding Glass Doors
Signs you need it
If the sliding door faces an open yard or pool and sits within range of hail-driven debris, impact-rated glass is the upgrade that holds.
What it costs in Southlake
Impact sliding glass doors in Southlake run $3,200 to $6,500 per opening, with laminated glass and reinforced frames included.
How we do it
We confirm the design pressure rating for the exposure, order the heavier laminated panel, and install with reinforced top track and sill anchorage through the frame into structure.
What Sliding & Patio Doors Costs in Southlake
| Item | Typical range in Southlake |
|---|---|
| Standard patio door (per opening) | $1,800 - $3,500 |
| Impact sliding glass door (per opening) | $3,200 - $6,500 |
| Sliding glass door replacement (per opening) | $1,500 - $3,000 |
Why does my Southlake sliding door keep binding?
Binding is almost always slab movement beneath the track, not a door defect. Clay soil expands and contracts seasonally, and a door that slid perfectly in January may catch by July. A threshold adjustment or re-hang is part of any proper Southlake quote.
Can you replace just the glass in my patio door?
Sometimes, but if the frame has already racked from soil movement, a glass-only replacement doesn’t fix the bind. We’ll tell you what we found after measuring, and the written quote covers exactly the work needed. Call (509) 265-6387.
Impact Garage Doors in Southlake

Impact garage doors in Southlake are common on homes where the garage faces the street and takes the brunt of spring hail storms. A standard steel door dents and deforms; an impact-rated door keeps its face. Our Impact Garage Doors work pairs wind-load rated panels with reinforced track and heavier operators, specified to the actual opening size.
Hurricane-Rated Garage Doors
Signs you need it
Visible dents from the last hail event, or a door that flexes inward during high wind gusts on a street-facing elevation, are the reasons to upgrade.
What it costs in Southlake
Hurricane-rated garage doors in Southlake run $2,800 to $5,500 per door, depending on width, insulation level, and wind-load rating.
How we do it
We measure the opening span and height, confirm the wind-load requirement for the exposure, order the rated panel, and install with reinforced track and heavier springs matched to the door weight.
Garage Door Replacement
Signs you need it
A door that’s structurally sound but cosmetically finished, or one with failing springs and a worn track, is usually a full replacement rather than a patch job in Southlake.
What it costs in Southlake
Standard garage door replacement in Southlake runs $1,500 to $3,800 per door, with the final figure set by insulation and panel gauge.
How we do it
We remove the old panels and track, confirm the opening is square, install the new door system with fresh track, springs, and weather sealing, then test the full travel cycle and safety reverse.
What Impact Garage Doors Costs in Southlake
| Item | Typical range in Southlake |
|---|---|
| Hurricane-rated garage door (per door) | $2,800 - $5,500 |
| Standard garage door replacement (per door) | $1,500 - $3,800 |
| Wind-load code compliance upgrade (per door) | $800 - $1,800 |
Do Southlake building codes require wind-rated garage doors?
Southlake follows Tarrant County and Texas wind-load requirements, and on some elevations that means a rated door. We’ll confirm what applies to your specific street exposure and write it into the quote before any work starts.
Will an impact garage door insulate my garage?
Impact-rated panels often include a polyurethane core, which adds thermal resistance beyond a standard single-skin door. For a Southlake garage that faces afternoon sun, the insulation benefit is real. Call (509) 265-6387 for a written estimate.
Custom & Geometric Windows in Southlake

Custom and geometric windows are the default in Southlake, not the exception. Arched transoms over entry doors, trapezoids above staircase landings, and two-story fixed panels in great rooms all need to be recreated to the original opening. Our Custom & Geometric Windows work starts with a template of the existing shape, not a guess from a photo.
Arched & Curved Windows
Signs you need it
Fogged glass in an arched transom, or a failed seal on a curved-top unit, means a custom remanufacture because no stock replacement exists.
What it costs in Southlake
Arched and curved window replacements in Southlake run $900 to $2,200 per unit, depending on radius, glass package, and frame finish.
How we do it
We take a physical template of the radius and spring line, confirm the mullion profile, order the matching unit, and install with the same sightline alignment as the original.
Oversized Openings
Signs you need it
Two-story fixed panels with visible seal failure, or cracked glass on a tall stairwell window that can’t be reached safely from inside, need an experienced crew with proper lift equipment.
What it costs in Southlake
Oversized window installation in Southlake runs $1,800 to $4,500 per unit, with the final figure set by glass size, height, and access.
How we do it
We engineer the lift plan, confirm the glazing weight, remove the old unit, and set the new panel with proper temporary bracing until the perimeter seal cures.
What Custom & Geometric Windows Costs in Southlake
| Item | Typical range in Southlake |
|---|---|
| Arched / curved window (per unit) | $900 - $2,200 |
| Geometric / shaped window (per unit) | $800 - $2,000 |
| Oversized fixed panel (per unit) | $1,800 - $4,500 |
How do you match the original geometric shape exactly?
We template the opening with a physical pattern, not just measurements. That template travels to the manufacturer so the new unit matches the original radius, leg length, and mullion layout. The customer keeps the measured survey.
Can you replace one pane in a two-story fixed window?
On an insulated glass unit, the entire sealed unit gets replaced, not a single pane. For a Southlake two-story panel, that means scaffolding or lift access. We quote that access cost in writing before work starts. Call (509) 265-6387.
Brands We Service in Southlake
We install and service window and door systems from CGI, CWS, ES Windows, and ECO Window Systems, among others. The choice is driven by the opening’s performance requirements and budget, not by what’s in a warehouse. See our brands for the full line detail.
